We will again use the
BankAccount class from the previous problem. You should be able to use the same definition for both problems.
Of course, a bank with only one account will go out of business, so we want our
BankAccount class to work correctly with many accounts. Naturally, each bank account should have its own balance, with deposits and withdrawals going to the appropriate account. Similarly, the penalty fees for each account should be kept separate.class BankAccount:
def __init__(self, initial_balance):
"""Creates an account with the given balance."""
…
def deposit(self, amount):
"""Deposits the amount into the account."""
…
def withdraw(self, amount):
"""
Withdraws the amount from the account. Each withdrawal resulting in a
negative balance also deducts a penalty fee of 5 dollars from the balance.
"""
…
def get_balance(self):
"""Returns the current balance in the account."""
…
def get_fees(self):
"""Returns the total fees ever deducted from the account."""
…
Here's one possible test with multiple accounts. It should print the values 10, 5, 5, and 0.
account1 = BankAccount(10)
account1.withdraw(15)
account2 = BankAccount(15)
account2.deposit(10)
account1.deposit(20)
account2.withdraw(20)
print account1.get_balance(), account1.get_fees(), account2.get_balance(), account2.get_fees()
Copy-and-paste the following much longer test. What four numbers are printed at the end? Enter the four numbers, separated only by spaces.
account1 = BankAccount(20)
account1.deposit(10)
account2 = BankAccount(10)
